      @axphysics Sir I have a doubt, If a cube of mass m hits a rigid point on earth and rotate about that point. Due to which torque it is rotating as mg will make it anticlockwise and N which is at its edge is also passing through the rigid point so no torque, Due to impulse no torque so as also it is passing through the rigid point. How it is possible.Which force is rotating it

    • @axphysics
      @axphysics 19 วันที่ผ่านมา

      @ChaitanyaSingh-w3i N will produce torque about centre of mass. So if you take axis through com, torque due to N will make it rotate. If you take axis at the point on the edge where N is acting, then mg will produce torque.
